Not a single Pole in any US currency, paper or metal.
The Irish are also important in US history, too.
Most people don't have any idea of the role they played, or the discrimination they faced, or the contributions they made. At best, they lump them, Polish and Irish, in with "anglos."
Lumping the Irish and Poles in with anglos is like calling African-Americans "Australian aborigines" because of a similarity in skin color or calling all Mexicans "Spanish" because of their language. I mean, it's already offensive to call Salvdorenos "Mexicans", but it's not lke the Salvadorenos are more different from Mexicans than Poles are from British or even Czechs. In the case of Irish, it's especially demeaning and offensive because most Irish in the US came over as a result of oppressive British--"Anglo-Saxon"--policies.
About 10.5% of Americans report having some Irish ancestry, so they're not far behind African-Americans as a percentage of the population at probably #4. (Af-Am is #3 in rank, after all). Polish, only about 3%.
Of course, we can just say "race is the criterion" and ignore a lot of history. And Salvadoreans and Brazilians are Mexican.
Tubman and most of the other names circulating for women on paper currency also had little to do with the founding of the US government or its earliest years, so let's not have that be a criterion. It's not the inclusiveness that's the problem, it's the selective inclusiveness, at least for me, and the striving for some argument that can then be taken as the original premise in order to justify the selectivity and selection(s).
